11 Claims.

This invention relates to slides for sashes, such as window sashes, togetherl with the complementary sashes for use with such slides.

Window sashes of ordinary type are usually mounted for sliding upward and downward in oppositely grooved frame members, there ordishrinkage, where wooden sashes are used, ordi-v narily so loosens the sashes in the window frame that they rattle between the rails and additionally pull away from the frame itself leaving edge spaces through which air may-enter in very considerable amounts, extremely objectionable during cold weather, it ordinarily being found necessary to put felt or rubber strips along the rails to prevent such rattling and prevent undesired entrance of air.

If the rails themselves so closely confine the sash as to prevent rattling when the sashes are dry, swelling due to rain of both rail and sash practically immobilize the sash and are a source lll of constant trouble, and even where metal sash and rails are employed it is extremely diliicult to accomplish that nicety of adjustment which will provide necessary tightness and at the same time allow free sliding movement.

The weight of the sash is counter-balanced by springs or weights in order that the-sash may remain at the position to which it is shifted or raised and in extremely heavy sash such provision will ordinarily still have to be made.

The objects of the present invention are:

To provide means for so mounting the sash in the frames that they will be substantially sealed line I-I of Fig. 2 adjacent the edge of the sash and looking toward the frame at one side of the Window.

Fig. 2 is a typical crosslsection taken as on lili,k

the line II--II of Fig. 1 showing a portion of the Window frame and fragmentary portions of the side edges of the lowerl sash and an additional sash, such as a screen.

Fig. 3 shows the oppositely faced frame member with modified means for securing the exble slides in place; and

Fig. 4 an additional securing method therefor.

Fig. 5 shows an edge view of a fragmentary portionA of a sash. and adjustable roller means for tighteningv or loosening the slide in the groove of the sash, and for increasing or decreasing friction' in such groove point; and

Fig. 6 a similar xed position roller.

Fig. 7 is a typical horizontal cross section of a fragmentaryv portion of a window, taken as at only; Fig. 8 being a sectional elevation taken as on the line VIII-VIII of Fig. 9, showing-a face view of the side rails of an upper and lower sash and a section of the window frame against which the edges of the sashes abut.

Fig. 9 is a sectionA taken as on the line VII- VII of Fig. 8, with the upper sash movedv to overlapping relation with the lower sash; and Figs. l0 and l1 are additional sections showing. modications in the positioning of the supporting slide.

Referring now to the drawings in which the various parts are indicated by numerals:

ll, I3 and l5 are respectively side, top and bottom rails of the bottom sash of a window frame. Il and I9 are respectively a portion of the side and the bottom rail of the top sash and 2l, 23 and 25 the side, top and bottom rails as of a screen sash. 21, 29 and 3l are respectively window frame membersbetween an opposite pair of which the window sashes and screen sash are disposed.

In my device, thin flexible strips 33, 35 and 3l extend preferably from top to bottom of the window frame, these strips, hereinafter designated as slides, being preferably thin, flat strips of resilient metal, though they may be thin, flat strips of resilient plasticv or other suitable material. Preferably the. windowframe members are slotted from top to bottom and the slides driven tightly into the slots until a desired amount only is left projecting, the slots, as the slot 39 in the window frame 21, being preferably deeper than the' inserted portion of the slides to provide necessary, or desired, adjustment. These slots extend straight from top to bottom of the sash so that the slides, as the slides 31 held by the slot 39, are initially straight, and insofar as that portion which is in the slots is concerned, are maintained by the slots in such straight line. The edges of the slots, as the edges 4l and 43 of the slot 39, are preferably rounded to vpermit somewhat greater transverse flexing of the slides. The slots for the slides may be largely, or entire ly, accomplished by strips 49, 40-A, and 4t2- B which are secured against the slides after they are placed, as by nailing to the groovefmember 2T, or in any other usual or desired manner.

In Fig. 3, slides .S3- A, 35-A and 3`l-A are shown as secured by moulding strips 45, 41 and 49 respectively, which strips may be secured in place, as by nails or brads, as the brad 5| shown securing the slide 49. These strips may be faced, as is the strip 45, with resilient material 53, and if desired the slot broadened and also faced by an opposite strip 55 of similar material, this material being a material such as soft rubber or Water-proof felt which will permit a certain amount of lateral displacement of the slide. If desired, as shown in Fig. 4, the slides 33-B, 35-B may be the opposite lfianges of a channel secured in place to the frame member3l by screws, as the screw 5l; or the slides, as the slide 31-B, may be one of the legs of an angle similarly secured.

It is preferred that the slides extend continuously from top to bottom of the window frame, and they are thus shown. It is obvious, however, that it may not be possible to assemble the sashes in the frame where continuous slides are used unless it be done at the time the frame is being constructed, and in such event, it may be found necessary to form the slides each in two pieces, one of which would be inserted, for example, above the top of the bottom sash, the sash raised and the -lower half of the slide put in place, but such being an obvious construction is not here shown.

The edges of the side rails, and the ends of the top and bottom rails of the sashes are grooved from top to bottom with iiatly arcuate grooves 59, El and 63 respectively, the section plane on which Fig. 1 is taken cutting these grooves, but not the slide; and Fig. l showing the groove curvature and the relation of the slides therein. The grooves are of the cross section shown in Fig. 2, being wider than the thickness of the slides, and preferably having one side inclined.

The slides as deected may lie against and hug The grooves also are that side of the groove. deeper than the slides and the approach edges of the grooves are preferably rounded.

About midway longitudinally of the grooves, pins 65, El and 69 are inserted on the convex side of the gro'oves 59, 6l and 63 respectively to deect the slides 33, 35 and 3l laterally out of line toward and slidably against the concave sides of the grooves, this causing the slides to hug the grooves from top to bottom of the sash and seal against passage of air.

In Fig. 6 a roller ll is shown as used in place of the pin for deflecting the slide 13.

In Fig. 5 a similar roller I5 is shown mounted in a rotatable head 16 which may be turned to increase or lessen the pressure of the roller on the slide 11. y l

In use, the sash may be raised or lowered, the pin or roller sliding or rolling, as the case may be, alo-ng the slide and holding that part of the slide within the upper and lower confines of the sash slidably against the concave side of the slot.

It will be obvious that the opposite sides of the sash are similarly mounted, though the slides only are shown.

In Fig. 7, slides 33-C, 35-C are shown as secured in suitable slots'in stiles 19 which slidably confines the side rails |l-C, l'l-C of the lower and upper sash respectively against an interposed or center stile 8|, the slides projecting from the stiles into grooves 59-C and 6l--C which correspond substantially to the grooves 59 and 6i of Figs. 1 and 2, except that they are cut into the front and back faces of the sash rails, rather than into the edges of these railsI as previously shown.

In Figs. 8 and 9, slides 33-D, 35--D are shown which are free throughout their length from edge engagement, the slides being secured at their respective upperl and lower ends as by screws 83 to the window frame members 2'l-D. The slides preferably are stretched and tightened, and at the same time spaced outward from the frame members by blocks, as the dowel pins 85, which are forced under the slides after the slide ends have been securely fastened.

rIhe faces of the sash rails ll-D, II--D are channelled from top to bottom with grooves 59D, SI-D respectively, which grooves extend arcuately from top to bottom of the sash, the grooves bowing, or convexing away from the frame Z'I-D as they extend toward the mid point of the sash from top and bottom. Adjacent the top of the lower sash, and, though not shown, the bottom of the upper sash, is a roller, as the roller 'II-D which .confines the strip 33-D against the convex side of the groove at the top end of the sash, confining at the lower end being accomplished by displacement of the slide away from the frame as the lower end of the sash approaches the lower secured end of the slide. 8l is a cut-away portion or chamber at the bottom of the lower sash in which the groove 59-D terminates, a similar chamber 8'I-A being provided at the upper end of the upper sash.

Fig. 10 shows a substantially identical arrangement, except that the slides 33-D, 35-D are laterally at right angles to the frame, and are fastened at their upper and lower ends to the center stile 8 l-E, and the grooves 59-E and BI-E are conformingly in the edges of the sash H-E, l1-E.

Fig. 11 shows a single slide 33-F for two sashes, the slide being of Width to span between the sash I I-F and I'l-F and into facing grooves 59--F, BI-F respectively cut therein.

It will be understood that the slides 33-D, 35-D to 33-F inclusive may be of other cross section than thin and flat, provided only that they be resilient and flexible.

In this form of the device the sashes are supported in desired position by frictional engagement of the slides with the sash grooves and may be shifted at will to desired positions.

It will be understood that in all forms of the device the sash shifts straight upward and downward along the slides Without lateral deviation of the sash.
